Foreign experts on the Marichka underwater droneHow Ukraine's SBU carried out its latest Crimean Bridge attackThe explosion of the structure, around which Russia had built a true cargo cult, took place on June 3 at 4:44 a.m. According to the Security Service of Ukraine (SBU), the operation had been months in the making. Agents planted explosives on the bridge supports and later activated them without any civilian casualties.Ukrainian special forces say the underwater supports were heavily damaged at the seabed level using 1,100 kg of explosives in TNT equivalent. The SBU reported that the bridge is now effectively in critical condition.“It’s extremely important to understand that the explosion was carried out at the seabed, at a depth of about 10 meters. That’s why there was no fire show like in previous cases. The real condition of the support structure can only be assessed during diving operations. Moreover, this also means that any repair work will be correspondingly difficult,” Defense Express described the special operation.The authors of the article raised questions about the method used to strike the bridge, pointing out the logistical and technical challenges involved.“Placing over one ton of explosives — just the explosive material itself, without casing — would have been nearly impossible for divers to achieve,” Defense Express experts noted. “One of the few realistic scenarios involves the use of underwater drones. This theory gains weight especially considering the recent lack of public information about such systems, despite their clear potential.”Among the most likely candidates named in the article is the Marichka underwater drone.This view is shared, for example, by Valerii Riabykh, Director of Development at the information and consulting company Defense Express.“Since there are more powerful explosives available, the actual weight might have been closer to 500 kg. Some experts now speculate that an underwater guided drone, like the previously shown Marichka, could have been used,” the military expert noted on Espreso TV.What is the Marichka droneMarichka is a multipurpose strike underwater unmanned vehicle of Ukrainian production. The drone is designed to engage a wide range of targets — boats, ships, bridge supports, and coastal fortifications. It can also be used for reconnaissance or cargo transport.Marichka was developed by the AMMO.UKRAINE volunteer team. The creators of the platform stated that they united Ukrainian scientists, analysts, and military experts to create an Army of Underwater Drones, with the large autonomous submarine Marichka as its foundation.On August 24, 2023, the successful testing of the new strike drone was announced — for the first time, an underwater one. A few days later, on August 29, a video of the test was released.“We are confident that after Marichka’s first strike, the Russian fleet will leave the Black and Azov seas and retreat to the Caspian,” Focus quoted the drone’s creators as saying.The exact technical specifications of the underwater unmanned vehicle are not disclosed for security reasons. Most likely, it will use electric propulsion, as the developers have already purchased a large batch of batteries.Known characteristics of the Marichka droneLength – 6 m,Width – 1 m,Range – up to 1000 km,Cost per unit – approx. $400,000Marichka underwater drone: key advantagesThe manufacturers highlight Marichka’s low noise level and stealth. Additionally, the drone carries powerful ammunition and can resist enemy electronic warfare systems. AMMO.UKRAINE dedicated a special video to Marichka’s advantages, emphasizing the following points:Safety. The absence of a crew makes the drone safe for personnel and does not put them at risk. Remote control means no injuries or fatalities.Stealth. The underwater combat machine is very difficult to detect and destroy; it remains invisible to many radars, scanners, and sonars.Autonomy. Marichka can “lie in wait” underwater, conserving energy while waiting for a target, then activate either by timer or operator signal.Range. The drone can travel over 1,000 km, a distance unreachable for many missiles and torpedoes.Payload capacity. The underwater drone’s large size allows it to carry a large combat load. The payload can exceed one ton over distances of more than 1,000 km. If the distance is reduced, it allows for even greater payload capacity.Versatility. Marichka is multifunctional, so it can be used not only for attacks but also for reconnaissance or cargo transport.Effectiveness. Developers call this the most important advantage. A year ago, they emphasized Marichka’s ability to destroy underwater objects, including bridge supports. Russia ignored this information back then.Foreign experts on the Marichka underwater droneAfter the official information about the drone Marichka appeared, the Naval News website, dedicated to naval enthusiasts, published a piece about this weapon. In particular, the article’s author, former Turkish Navy officer and naval combat expert Tayfun Ozberk, believes that a drone of this type, which targets the underwater parts of ships, could become a far more destructive weapon than surface aquatic drones of the boat type.“Underwater drones are even more dangerous to Russian BSF (Black Sea Fleet - ed.) assets because they cannot be detected by the Russian surveillance system. While it is not known how much explosive Marichka can deliver to the target, given the size of the drone, it can be assumed that it has a significant amount of explosives on board. Moreover, Marichka will hit the ships on the underwater part, which can be even more destructive for the warships. A swarm of these suicide UUVs is very hard to defend,” wrote Tayfun Ozberk.British military analyst H. I. Sutton highlighted some interesting features of the device in his blog. According to him, one prototype has an X-shaped rudder configuration. He also noted the unusual nose cone at the front of the autonomous submarine prototype.“Among the many large AUV projects around the world, it is probably the first born directly from wartime needs” the author emphasized.

I have some voice clip files (still currently `.wav` files) and I have all the documented names in my notes, but I'm unsure on what some of them do, which is why I haven't converted any of them into `.ogg` files yet. A list of what my best guesses are on how each voice clip is used: * `attack1.ogg` - Plays when using an item? * `attack2.ogg` - Plays when using an item? * `boost1.ogg` - Plays when performing a boost. * `boost2.ogg` - Plays when performing a...

Godot Version: 4.4 Hello everyone, I’m new to Godot and gamedev in general and right when I found I was very close to understanding AnimationStateMachines, I found some huge trouble. I’ll attach a screenshot of my AnimationTree and do my best to explain what’s happening. My goal: The player has two attack animations and it always starts with attack1, but if another attack is queued before the recovery animation ends, it will use the attack2 animation instead When I left click I set a variable called is_attacking to true. This causes the StateMachine to switch from idle to attack1. At the end of the attack1 animation, an animation track calls a method that sets is_attacking to false. attack1 always progresses unconditionally to attack_recovery_buffer, and since is_attacking is now false, the player can click again to set it back to true. attack_recovery_buffer always progresses unconditionally to attack_recovery; from here it progresses immediately to attack2 if is_attacking == true (priority 0), otherwise it progresses to idle (priority 1). From here the tree behaves the exact same as the previous part, except after recovery it goes to attack1 (instead of attack2) if the player attacked again. Now here’s my issue: despite the fact that is_attacking seems to follow the intended state flow, my AnimationTree is not behaving as expected. When it reaches attack_recovery it goes to idle and then immediately to attack1, staying in a loop forever, indicating that is_attacking is still true. However, if is_attacking was true, attack_recovery should have progressed to attack2. If I put the condition !is_attacking on the transition between attack_recovery and idle, the animation gets stuck on the last frame of attack_recovery, indicating that it can’t progress to attack2 (which requires is_attacking to be true) nor to idle (which requires is_attacking to be false, in this case). Given boolean variables only have two possible values, I guess this is a problem with how/when the StateMachine evaluates switch conditions, but I can’t for the life of me figure out what the problem is precisely. This is the entirety of the code that handles my player movement: extends Node2D @export var player: CharacterBody2D @export var speed: float = 8.0 @export var jump_power: float = 12 var speed_multiplier: float = 30.0 var jump_multiplier: float = -30.0 var direction: float = 0.0 var friction: float = 3.0 var is_attacking: bool = false func _input(event: InputEvent) -> void: if event.is_action_pressed('attack'): is_attacking = true elif event.is_action_pressed('jump') and player.is_on_floor(): player.velocity.y = jump_power * jump_multiplier func _physics_process(delta: float) -> void: if not player.is_on_floor(): player.velocity += player.get_gravity() * delta direction = Input.get_axis("move_left", "move_right") if direction: player.velocity.x = direction * speed * speed_multiplier else: player.velocity.x = move_toward(player.velocity.x, 0, speed * friction) player.move_and_slide() func set_weapon_collision() -> void: # collision logic print('collision set') func unset_weapon_collision() -> void: # collision logic print('collision unset') func stop_attacking() -> void: is_attacking = false unset_weapon_collision() The method called at the end of attack1/attack2 is stop_attacking. I tried putting the call anywhere, but the result doesn’t change. Thanks in advance.

it looks something like this. can you explain the concept here. visualize with me. is the attack button the same as run button or are they separate buttons var button_presumed = false func _process(_delta: float) -> void: if Input.is_action_just_pressed("attack2"): if button_presumed == true: attack() else: return if Input.is_action_released("run"): $"."./Knife".queue_free() button_presumed = true if Input.is_action_pressed("run"): $"."./Knife".show() $"."./Knife".queue_redraw() if $"."./Animations".flip_h == true: $"."./AnimationPlayer".play("Knife_(LEFT)") if $"."./Animations".flip_h == false: $"."./AnimationPlayer".play("Knife_(RIGHT)") if $"."./AnimationPlayer".animation_finished: $"."./Knife".hide() button_presumed = false

Godot 4.3 Hello! I have been trying for hours and nothing seems to fix this, I’m trying to make it where if the Sprint button is being pressed, then the attack button is disabled, I’m not sure how to do this. Could someone please help? func _process(_delta: float) -> void: if Input.is_action_just_pressed("attack2"): if Input.is_action_just_pressed("run") == true: $"../Knife".queue_free() if Input.is_action_just_pressed("run") == false: $"../Knife".show() $"../Knife".queue_redraw() if $"../Animations".flip_h == true: $"../AnimationPlayer".play("Knife_(LEFT)") if $"../Animations".flip_h == false: $"../AnimationPlayer".play("Knife_(RIGHT)") if $"../AnimationPlayer".animation_finished: $"../Knife".hide()
